Decent & Affordable enhancement lenses for phone p
I really dig this kit. Used throughout Nepal & India for a month of traveling, it worked well for getting wide-angle views of tight places. Used for video as well as photos. Well designed and decent glass optics.

Just the greatest!
This a gift for my daughter in law who is a photographer. I can't wait to give it to her. It is just great and actually looks like the real thing. It is made very well and of sturdy material. Love this item.

Very nice
I found myself using these more often (90%) than my Sony WH-XB900. The Sony have more bass and sometimes is too much for me.The Major IV have a nice balanced sound, highs mediums and lows can be clearly heard without exaggeration or overwhelming. I guess if I wanted I could mess with EQ and pump +1db or +2db some low frequency but I am starting to appreciate music in more natural unaltered way. If I am craving for some heavy low frequency I can always switch to WH-XB900 but I haven't had the need for that.They are also lightweight and easy to carry. These are my daily headphones since about 5 months and I have no plans to change them
